Salt on the Roads


Salt on the Roads
One of the reasons our bridges are rapidly deteriorating is the use of salt on the roads. Any new infrastructure legislation needs to solve this problem first. I have two suggestions. Stop using salt to melt ice. Not only does it rust mild steel bridge trusses, it scales the surface of concrete and washes into nearby streams. One substitute might be fly ash from power plants or perhaps some newly created substance easier on the environment. Second idea is to insist that new bridges use a rust resistant steel such as Corten or stainless steel. More expensive, only in the short run. New concrete used needs to be sprayed with a coating resistant to salt, probably after construction. Another idea is to stay home on snow days and telecommute using your home computer or otherwise stay home. If you must travel then use vehicles equipped to do so in snow. We need to deal with salt on the roads before we spend billions on infrastructure only to have it rust away again in thirty years
